EPECIPICATION forming part of Letters Patent No. 326,481, dated September 15, 1885.

Application filed May 12, 1884. (No model.)

1' 0 all whom it may concern:

Be it known that I, LUOIUS L. CULVER, of the city of St. Louis, in the State of Missouri, have invented a certain new and useful Improvement in Grates for Stoves, Ranges, &c., of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification, and in which Figure 1 is a perspective view. Fig. 2 is a detail vertical section of a range or stove, showing the grate in side view. Fig. 3 is a perspective view of one of the sections forming the sides of the fire-box, and Fig. 4 isan inside View of the connecting-bar of the grate. I

My invention relates to the manner of forming and shaking the grate, described.

' My invention consists in features of novelty pointed out in the claims.

Referring to the drawings, A represents part of a range or stove, and B the waterback.

0 represents the fire-box supported in the usual way, the sides of which consist of short sections D, that fit beneath the watel back, and front plates I, that fit against the ends of the water-back, as shown in Fig. 2. The sections are held, by means of suitable notches, J, and lugs or projections L of any desired shape or form, between the water-back and bottom of the box, and the plates I are held in the same way between the bottom of the box and the sides of the range or stove. The plate and sections are shown removed on one side of Fig. 1. By removing the plates the sections can be moved forward and taken out and replaced by others or put back themselves.

The grate consists of two or more sections, M, each formed of a cross-bar and radial arms, the arms of one projecting between those of another, as shown in Fig. 1, so that when the grate is shaken every inch of the contents of the fire-box is moved and thoroughly stirred up, and the outer arms of the end sections fit between similar arms on the ends of the bottom of the fire-box. The sections have gudgeons or arbors N that fit in re as hereinafter fully' cesses in the bed-plate at the bottom of the firebox, as shown. 7

On one gudgeon of each section is a crank, 0, extending downward and having a round projection, P, on its lower end. (See Fig. 4.) On the outer end of the projection is a button or head, T. This button or head is removed in the center of Fig. 4 to show the round projection.

The cranks are connected by a bar, U, having large openings U to receive the buttons or heads T,with small extensions U, in which the projections fit when the bar is in place. The bar is thus held from getting off the projections by the buttons or heads.

Connected to the front end of the bar, pref erably by a pivot'pin, V, is a handle, V, that extends through an opening, A, in the wall of the range or stove. The handle has a notch, V on its lower edge that engages the wall of the range or stove when the handle is not raised up, thus preventing the grate from being accidentally dumped. By raising the handle until the notch V is disengaged from the wall, and no farther, it can be pulled outward, dumping the grate into the position shown by dotted lines, Fig. 2.

In the upper edge of the handle is a long notch, V, and by raising the handle until this notch comes against the top of the opening, as shown in Fig. 2, the grate can be shaken, but not dumped.

I claim as my invention 1. In a range or stove, a grate consisting of two or more sections made with interlocking arms and gudgeons that rest in notches in the bed-plate at the bottom of the fire-box, cranks upon the gudgeons at one side of the box, a bar connecting the cranks, and a handle connected to the bar and extending out through an opening in the wall of the range or stove, and having notches on its lower and upper edges that engage with the wall, the lower one to prevent the grate being accidentally dumped and the upper one to limit the shaking of the grate, as set forth.

2. In a range or stove, a grate consisting of two or more sections provided with interlocking fingers or arms and having gudgeons resting on the bed-plate at the bottom of the fire-box, cranks upon the gudgeons at one side of the box, projections with buttons or heads on the lower ends of the cranks, a bar having opening to receive the buttons or heads, and projections to connect the cranks, and a handle connected to the bar and extending out through an opening in the wall of the range or stove and adapted to be pulled out to dump the grate, to be shaken with a limited movement, and to hold the grate from 10 being accidentally dumped, substantially as set forth.
